FIGS. 6A to 11B are reference diagrams illustrating the operations of changing the AR graphic object according to one embodiment of the present disclosure.

As illustrated in FIGS. 6A and 6B, the processor 270 may display AR graphic objects 610 and 620 at a point in the display area corresponding to the specified first point together with the image in front of the vehicle. The image in front of the vehicle may be acquired by at least one of the AR camera 225 and the object detection device 110. The processor 270 may display arrow images 610 and 620 on a point of an intersection in the image in front of the vehicle. The directions of the arrow images 610 and 620 may indicate a rotation direction of the vehicle 100 on a path at the intersection.

The processor 270 may change the first AR graphic objects 610 and 620 based on distance data between the vehicle 100 and the first point. The processor 270 may gradually increase the arrow images 610 and 620 as the vehicle 100 approaches the intersection. The processor 270 may gradually move the arrow images 610 and 620 in the direction in which the arrow is directed as the vehicle 100 approaches the intersection. For example, when a right turn path is set at an intersection, the processor 270 may continuously move the arrow from the left to the right of the display screen while displaying the arrow image 610 gradually larger as the vehicle 100 approaches the intersection. For example, when a left turn path is set at an intersection, the processor 270 may continuously move the arrow from the right to the left of the display screen while displaying the arrow image 620 gradually larger as the vehicle 100 approaches the intersection.

In this way, by changing the sizes and positions of the arrow images 610 and 620, it is possible to prevent a user from recognizing an erroneous display or shaking of the AR graphic image.

As illustrated in FIGS. 7A to 7B, the processor 270 may adjust the degree of change of first AR graphic objects 710 and 720 based on at least one of the accuracy for the first point, the data on the vanishing line, the data on the curvature of the traveling road, and the motion data of the vehicle.

The processor 270 may determine the accuracy of the first point based on the DOP data information of the GPS data. The processor 270 may determine the accuracy of the first point based on the vehicle 100 received from another vehicle and the position data of the first point through the communication device 120. The processor 270 may determine the accuracy of the first point based on the sensing data for the first point acquired by the object detection device 110.

Compared with when the accuracy for the first point is high (as in FIG. 7A, the accuracy is a first reference value or more), when the accuracy for the first point is low (as illustrated in FIG. 7B, the accuracy is less than a second reference value), the processor 270 may move the first graphic object so that the movement distance is larger. Compared with when the accuracy for the first point is high (as in FIG. 7A, the accuracy is a first reference value or more), when the accuracy for the first point is low (as illustrated in FIG. 7B, the accuracy is less than a second reference value), the processor 270 may move the first graphic object so that the moving speed is faster.

Compared with when the vanishing line is located below a center line of a screen in a horizontal direction, when the vanishing line is located above the center line, the processor 270 may move the first graphic object so that the moving distance increases. Compared with when the vanishing line is located below the center line of the screen in the horizontal direction, when the vanishing line is located above the center line, the processor 270 may move the first graphic object so that the moving speed is faster.

Compared with when the curvature of the traveling road is large, when the curvature of the traveling road is small, the processor 270 may move the first graphic object so that the moving distance increases. Compared with when the curvature of the traveling road is large, when the curvature of the traveling road is small, the processor 270 may move the first graphic object so that the moving distance increases.

Compared with when the movement of the vehicle 100 is small, when the movement of the vehicle 100 is large, the processor 270 may move the first graphic object so that the movement distance increases. Compared with when the movement of the vehicle 100 is small, when the movement of the vehicle 100 is large, the processor 270 may move the first graphic object so that the moving speed is faster.

As illustrated in FIGS. 8A to 8B, the processor 270 may adjust a height of the first AR graphic objects 710 and 720 on the screen based on at least one of the accuracy for the first point, the data on the vanishing line, the data on the curvature of the traveling road, and the motion data of the vehicle.

Compared with when the accuracy for the first point is high (as in FIG. 8A, the accuracy is the first reference value or more), when the accuracy for the first point is low (as illustrated in FIG. 8B, the accuracy is less than the second reference value), the processor 270 may display a first graphic object 820 at a higher point on the display screen.

Compared with when the vanishing line is lower than the center line of the screen in the horizontal direction, when the vanishing line is higher than the center line of the screen, the processor 270 may display the first graphic object at a higher point on the display screen.

Compared with when the curvature of the traveling road is large, when the curvature of the traveling road is small, the processor 270 may display the first graphic object at a higher point on the screen.

As illustrated in FIGS. 9A and 9B, when it is determined that there is no point corresponding to the first point in the display area, the processor 270 may display the first graphic object at a point closest to the first point in the display area.

The processor 270 may display only a partial area of the acquired image data in front of the vehicle on the display 251. In this case, the first point corresponding to the first graphic object may not be visible in the display area of the display 251.

When arrow images 910 and 920 are to be displayed outside the display 251, the processor 270 may display the arrow images 910 a and 920 a on the outer portion of the display 251. When connecting a center 901 of the display 251 from a point on the screen where the arrow images 910 and 920 should be displayed corresponding to the first point, the processor 270 may display the arrow images 910 a and 920 a on the outer portion of the display 251.

As illustrated in FIG. 10 , the processor 270 may determine the moving direction and the moving speed of the first AR graphic object based on the steering data of the vehicle 100.

The processor 270 may set a starting point 1001 and an ending point 1002 of the movement when the arrow image is moved in the right-left direction. As described with reference to FIGS. 9A and 9B, when the starting point 1001 of the arrow image is located outside the screen, the processor 270 may display the arrow image 1010 a on the outer portion of the display 251.

When the vehicle 100 moves in the right-left direction, the display 251 also moves in the right-left direction. In this case, arrow images 1010 a, 1010 b, 1010 c, and 1010 d and the display 251 move together. While the vehicle 100 moves to a right side according to a right steering input, the arrow images 1010 a, 1010 b, 1010 c, and 1010 d may be controlled to move to the right side. In this case, the movement of the display 251 may be faster than the movements of the arrow images 1010 a, 1010 b, 1010 c, and 1010 d. In this case, the processor 270 may move the arrow image to a left side of the display area based on the display area of the display 251.

Meanwhile, the processor 270 may decrease a moving speed of the arrow when the vehicle 100 does not move left and right, and increase the moving speed of the arrow when the vehicle 100 moves left and right.

As illustrated in FIGS. 11A and 11B, when an arrow image 1110 is out of the screen display area of the display 251, the processor 270 may display images 1120 and 1130 indicating a point at which the arrow image 1110 should be displayed. The processor 270 may display connection lines 1120 and 1130 when connecting the point where the arrow image 1110 should be displayed and the center point 251 of the display 251 in the display area. In this case, as illustrated in FIG. 11B, the processor 270 may further display an arrow shape indicating a display point of the arrow image 1110.
